Hello, 60-second science listeners. I'm Katie Hafner, the host of Lost Women of Science. Each season is devoted

to the life and work of one scientist who hasn't gotten the recognition she deserves.

We're calling this season a grasshopper in very tall grass, and it's all about Clara Don von Neumann.

Clary, as she was called by friends, was one of the world's first computer programmers.

I've been writing about computers for a really long time, more than 30 years, in fact.

I even wrote a history of the internet in 1996 called Where Wizards Stay Up Late. And the

wizards? All men. I've been on this beat for so long. I thought I knew all the major figures.

But then I stumbled upon Clara von Neumann's name this past year, and I drew a blank. How had I missed

her? When I asked some big hitters in the computer science world about her, they all had the

same response. Who? I couldn't shake this feeling that here was this truly lost woman of computing who was

nonetheless connected to very well-known histories and people. She was involved in nuclear

weapons research. She worked for Los Alamos. She coded for the Enniac, one of the earliest

electronic computers, and she ran in a circle of famous scientists.

People like Albert Einstein, J. Robert Oppenheimer, and her own husband, John von Neumann,

a famous Hungarian scientist who was considered one of the smartest people alive.

I thought Clary could teach us a thing or two about this time, the dawn of electronic computers

and nuclear warfare, and so we started digging.
